  • Met e 1 tropomyosin variants for use in allergen-specific immunotherapy
    Patent number: 10301365
    Abstract: The present invention provides isolated Met e 1 polypeptides and nucleic acids encoding the isolated polypeptides that can prevent and/or alleviate an allergic response to shellfish tropomyosin. The polypeptides are based on the shrimp tropomyosin Met e 1 protein and have been modified to act as hypoallergens. The Met e 1 hypoallergens have low to no IgE reactivity or allergenicity and are useful for prophylactic and/or therapeutic treatment of shellfish allergy in subject in need thereof.
    Type: Grant
    Filed: October 3, 2016
    Date of Patent: May 28, 2019
